General Description
The OV7670/OV7171 C
AMERA

HIP
TM
is a low voltage CMOS
image sensor that provides the full functionality of a
single-chip VGA camera and image processor in a small
footprint package. The OV7670/OV7171 provides full-frame,
sub-sampled or windowed 8-bit images in a wide range of
formats, controlled through the Serial Camera Control Bus
(SCCB) interface.
This product has an image array capable of operating at up
to 30 frames per second (fps) in VGA with complete user
control over image quality, formatting and output data
transfer. All required image processing functions, including
exposure control, gamma, white balance, color saturation,
hue control and more, are also programmable through the
SCCB interface. In addition, OmniVision C

proprietary sensor technology to improve image quality by
reducing or eliminating common lighting/electrical sources of
image contamination, such as fixed pattern noise (FPN),
smearing, blooming, etc., to produce a clean, fully stable
color image.
